Making dining reservations

How and where can I make a dining reservation? Want to try and get one for Finnagans on our HHN night before it opens.

I think the UOR resort restaurants use Open Table for reservations. Here's the website for Finnegans, and it looks like there's a link for reservations at the bottom.
